5 a day revision Energy and electricity What is efficiency? Explain why electricity is not a form of energy. What is efficiency? What is the law of conservation of energy? What do we use a Sankey diagram for? Describe the energy transfers that take place in a light bulb. Are they useful or not useful? How does this relate to efficiency? @aegilopoides

5 a day revision Energy and electricity What is energy payback time? What is voltage, how is it measured and what are its units? How would an increase in voltage affect a circuit? What is power? Describe the steps in producing electricity in a power station. @aegilopoides
